When you go to start the engine, the starter motor cranks the engine over up to approximately 4-500 RPM. Hopefully the engine will then fire up if it has the correct fuel and air ratio and the fuel is injected at the correct time.

What appears to be happening with your wifes car is the engine initially fires up as the starter motor cranks the engine over, but then loses the fuel injection pressure so the engine just stalls instead of picking up RPM to settle at the idle speed.

This is still the same problem you have been reporting for the last few months.

Going through the start proceedure the RPM needle just seems to get above 250 and below 500 and it just drops that is what ive noticed...

Going back to a intank pump possible problem with the non return valve wouldnt the lack of pressure show up on the system !

Plus lets say it is the intank tank pump is there anything that i should be looking at under the hood if i get the missus to start it in the morning!Isnt the intank pump before the fuel filter !If the fuel is being drawn back towards the pump where would the least amount of fuel pressure be....

For the RPM to indicate at all, the starter motor must have been turning the engine over but you say sounded like nothing was happening at all ?? The starter motor is fine if its turning the engine over. How long are you seeing 500 RPM or less. Doesn't the starter motor automatically stop turning if the engine has fired/started which I guess is above normal idle RPM etc

Fundamental, the engine starts but does not run. This manifestation has not changed.

I think we are all surprised that the mechanic/technicians who have ventured to look at this have no idea what it could be.

Kuga Titanium X Sport 180 Manual(AWD), Magnetic (with a few extras). March 2016.Makes you want to drive it, though not necessarily buy it.

Yep I remember the second one. Cant see why an experienced mechanic should not be able to check to see whether its fuel starvation (and whether fuel is being 'stopped' once its starts) or its not enough there to start with. The fact it does start straight away even on a restart suggest fuel is there immediately, so is something actually shutting the engine OFF? This was suggested before of course.

I have no idea how the shutdown takes place so cant offer any suggestions there, but again a mechanic particularly a Ford mechanic/technician should have this thought running through his mind when he sees that. Have they witnessed this, if not put the video on memory stick and let them see it.

Last night i had to go out to kuga to look for something that the missus dropped...So i started her up and like i have said before that the RPM needle just sat on the top edge of the 750 mark....So when i went back inside i said to the missus that the kuga wont start first time in the morning thus exaplining about the rpm needle...

And true to form this morning the kuga didnt fire up first time the rpm hit 500rpm and it almost started but the rpm Needle dropped back..The second attempt started straight away and the rpm needle sat higher above the 750rpm marker.....

Confused now....Managed to get a part number for the sender unit from evans halshaw 1633070..But i have now also found an official ford part seller that is selling the sender unit but its a different part number 1582806....

Which is the correct one........

Sorted it....The official part number is 1633070 and cant be bought from anywhere but ford...Non in stock at their depot and its on order which could take anything from 2wks to 2mths....Cost Â£305 and that incs vat.....
